area of a circle is pir^2
\[A=\pi(r)^2\]
where A is area, pi is 3.14 and r is radius

Answer 2

Okay.

Answer 3

okay so try to work it out, and show me wh at you get

Answer 4

Answer 5

Wait, I messed up.

Answer 6

12x3.14=37.68

Answer 7

\[A=\pi(r)^{2} \] can be written \[A=\pi(r)(r) \]

Answer 8

Right?

Answer 9

Okay.

Answer 10

so you multiplied by 12, to get 37.68
multiply your answer by 12 again

Answer 11

452.16?

Answer 12

yes

Answer 13

Okay.

Answer 14

Thanks. :)
